The American dream can be defined by whoever dreams it. It could be the dream of making money so you can afford comfort for yourself and your family just as much as striving to become successful in what you pursue. How possible or impossible it is, doesn’t make it unfit for the definition of “the American dream”. The only thing what makes it valuable at all is the self-accomplishment and happiness it causes the individual who chose to go after it. There are as many different dreams in terms of triumph, accomplishment and success as there are individuals. Though the only thing we have in common might be that we strive after the consequences of the dream, which are happiness and content with oneself. It’s a long way to the target but what keeps us going are the possibilities, hope or even curiosity. The beauty of knowledge is that it is undoubtedly easy to pass on despite its tremendous value. The value of knowledge can be translated into the everyday mundane simplification of matters that once used to burden people. From a variety of inventions to the exploration of space as portrayed in the case of Katherine Johnson. Katherine Johnson, before this Katherine Goble, lived in the US during the 50s. The despicable time of the rule of apartheid in everyday situations and places, like the bus, schools, and public toilets. In other words, Katherine didn’t have the equality or possibilities, she was both a woman and black in a time where both were at the bottom in every context.Ever since she was a young girl Katherine was fascinated by numbers. She used to count the steps to and from school and the number of dishes she’d wash. Katherine’s parents soon saw the gift she had for mathematics, her father worked hard and even the family moved to another city in order to provide Katherine with the education a mind like her deserved since the line of segregation was visible in the specific ‘all white’ and ‘all black’ schools. Katherine was able to skip ahead and she attended high school at the age of 10 and graduated by the age of 14 after which she entered West Virginia State College (now West Virginia State University). Being the first African-American woman to do so. After graduating with a degree in French and Mathematics, at the age of 18, Katherine became a teacher at a black public school in Marion, Virginia. She again enrolled in a graduate math program and continued her studies after quitting her job as a teacher. In the year 1952, she heard from a relative that NACA (National Advisory Committee for Aeronautics) was hiring mathematicians. She decided on a career as a research mathematician, despite the pushbacks she would accommodate. Johnson was offered a job in 1953 and she accepted becoming a member of the early NASA team. This team was often referred by Johnson as virtual “computers who wore skirts”. That’s where her contribution to the various space projects began. From 1958 until her retirement in 1986, she worked as aerospace technologist in the famous projects which were of great importance in the time of the race into space against the Soviet Union She calculated the trajectory for the 1961 space flight of Alan Shepard, who became the first American in space, also the launch window for his 1961 Mercury mission. She thoroughly plotted backup navigation charts for astronauts in case of electronic failures. When NASA used electronic computers for the first time to calculate John Glenn’s orbit around Earth, officials called on Johnson to verify the computer’s numbers; Glenn had asked for her specifically and had refused to fly unless Johnson verified the calculations.Despite all these achievements, Katherine never saw herself as more than the others. In her early years, her father had taught her this by saying: “You’re just as good as any of them, but you’re in no way better.”Breaking the norms like this, an African-American woman to succeed in a field dominated by men, purely through hard work and determination is the essence of what the American dream should be interpreted as, rather than the sum of money or recognition you receive from it. It wasn’t until 2015 when she was awarded the Presidential Medal of Freedom by President Obama and the year 2016 when her story was featured in the Global Award and Oscar-winning movie ‘Hidden Figures’. She has contributed to the very important first steps in space exploration and has become an inspiration not just to me, but to all the little coloured or non-coloured girls, a proof that you can make it despite what everyone else, society included, has in mind for your future.
